On the other side of the light, the head has some cooling fins cut into it, which are identical to those found on the Wurkkos TS10. That’s where the comparisons end, I promise. In another interesting move, the USB-C charging port is on what I consider to be the front of the light, above the make a model markings. The SC32 has a narrow rubber cover for the port, unlike other Sofirms which have a larger square cover. It fits fairly snugly, but is not too difficult to remove when you need to charge. Next to the charging port is a status light which stays on for 5 seconds when you first turn the light on, displaying in green when charge is good, solid red when it’s low, and flashing red when it’s critical. It also flashes red while charging.

The “head” section has deep cooling fins cut into the side, with the circular button at the front, above the Sorfirn name and model. On the reverse is the USB charging port and some regulatory markings. There is a tiny lip right where the tab on the USB charging port cover lays, so if you run your fingernail along the surface of the light to try and get it under that tab, you’ll hit that lip and it can make it challenging to grasp, but once you do, the cover lifts up easily. Press and Hold: Advance mode (You can advance out of moonlight and turbo to LMH, but not into moonlight or turbo.) The other accessory it comes with is a lanyard, but the only place to attach it is onto the end of the clip, which is closer to the head than it is to the tail. This sort of makes sense, as it allows you to rotate the light between standard and overhand grips, but it doesn’t really allow for the cigar hold, and you wouldn’t want it dangling by this. I measured 1240 lumens in turbo but that dropped to just over 1000 lumens in 10 seconds and 250 lumens at 30 seconds – far lower than spec’d. At 5 minutes it was at 138 lumens and at 10 minutes it was 102 lumens which it held for a couple of hours. That output when you turn it on is still pretty bright for a tiny torch even if it is just for a short time. And you can even increase the step down temperatures in Anduril which can increase runtimes slightly in the higher modes. I’ll discuss this briefly later. Also if you’re using these torches outside in cooler temperatures, you’ll also get better runtimes in the brighter modes. This switch also has indicating features – below it’s seen indicating red for low voltage. Notably, the switch will indicate for 5 seconds after the light is turned on, as follows:Advanced Temperature Regulation (ATR) technology: ATR will adjust the brightness level automatically when the driver temperature reaches a relatively high temperature to prevent overheating. I measured a colour temperature of 5846K with a very slight green tint that wasn’t really noticeable in most cases and a CRI of 65. There’s only one version of the Wurkkos WK03 flashlight but it’s available with or without the 18650 seen in this review. Price Chế độ Vừa: 350 lumen. Sáng ổn định, thay đổi nhẹ khó nhận ra trong suốt thời gian sáng đến khi tắt. The Nichia 519A LED sits inside a slightly mottled reflector and there is a noticeable hotspot, but with a fairly low output I still only measured 82 metres of throw with 1682 candela of intensity.

The Fenix PD25R comes with a USB-C to USB-A charging cable, spare o-rings, a lanyard, a user manual, and rather surprisingly a little mini pouch for your belt. The T1S uses the slightly less common 18350 battery – it’s the same diameter as an 18650 just shorter. As an aside the first two digits of these battery types refer to the diameter, and the second two digits the length – both in mm. I measured the colour temperature as a cool 6507K but with a very neutral tint and a decent CRI of 70. Amps were measured with a Klein Tools MM300 digital multimeter to the best of my ability. Battery Life: Runtime graphsMode Memory: memorizes the last brightness level used in the general modes (except Moon, Turbo and Strobe) One of the big selling points of this torch are the 3 high CRI 5000K natural white Nichia 519A LEDs. The interface is very easy to use. Press the power button to turn it on and then the mode button to cycle from ultralow 67 hour 1 lumen mode, to 21 hour 15 lumen low mode, 7 hour 65 lumen mid mode and the 2 hour 45 minute 200 lumen high mode. Press and hold the mode button with the torch on or off for the headline grabbing 4000 lumen turbo mode which is insanely bright for any torch let alone one this size. Press and hold the power button with the torch off to access ultralow mode. There’s no strobe function. The display shows the brightness level and time remaining for each mode. In turbo there’s a countdown progress bar that lasts up to 10 seconds depending on the temperature of the torch. You can keep pressing it but the torch gets very hot and the turbo lasts a progressively shorter time. The torch head got warm to the touch at around 46°C. The moonlight mode I measured at 2 lumens which is a bit bright for a moonlight mode but not too bad.
